This dissertation presents algorithms for data structures called distributed hash tables (DHT) or structured overlay networks, which are used to build scalable self-managing distributed systems. The provided algorithms guarantee lookup consistency in the presence of dynamism: they guarantee consistent lookup results in the presence of nodes joining and leaving. LÄS MER

Engineering design is fundamentally social, requiring much interaction and communication between the people involved. Additionally, good design often relies upon the ability of a cross-functional team to create a shared understanding of the task, the process, and the respective roles of its members. LÄS MER

Technology-sustained pervasive games, contrary to technology-supported pervasive games, can be understood as computer games interfacing with the physical world. Pervasive games are known to make use of ‘non-standard input devices’ and with the rise of the Internet of Things (IoT), pervasive applications can be expected to move beyond games. LÄS MER

Advances in Internet-of-Things integrate sensors and actuators in everyday items or even people transforming our society at an accelerated pace. This occurs in areas such as agriculture, logistics, transport, healthcare, and smart cities and has created new ways to interact with and experience entertainment, (serious) games, education, etc. LÄS MER
